Note:

This device has been designed to perform

to the parameters of its data sheet. It has

been tested to an electrical specification

designed to determine its conformance

with these parameters. Due to process

differences in the manufacture of this

device, this device may have different

performance characteristics than its earlier

version. These differences may cause this

device to perform differently in your

application than the earlier version of this

device.
